Good news and bad news.
I've been communicating with another expert on Hünsruck genealogy, and he confirmed that our Jacob was definitely born to Bernhard Mühleisen of Riesweiler, between 1721 and 1725. I resisted the Idea when it was given to me before because the name "Bernhard" was not repeated anywhere In subsequent generations. Given that fact, perhaps there was a schism between Jacob and his father. Maybe Jacob moved to America to get away from whatever the problem might have been.
I still believe the first generations of Mühleissens lived in Rheinböllen and Dichtelbach, but Bernard made his way to Riesweiler, where he was taxed In 1721 and still lived there up to at least 1742. Unfortunately, the Protestants in Riesweiler attended church in nearby Argenthal, and those records were destroyed in a 1796 fire set by occupying French soldiers. Thus we have very little more Information about Riesweiler births, deaths, and marriages.
However, there is a record of a brother to Jacob - Johann Peter Mühleisen. He was born in 1720 and died November 12, 1780 in Altweidelbach, where the record was found. He married Christina Müller on April 26, 1746. She was born March 21, 1723, and died on March 28, 1761 in Altweidelbach. They had at least four children.
The bad news here is that I'm personally responsible for the many online references to Dichtelbach Jacob, 1719. So I'm going to be spending a lot of time trying to correct those errant trees. If you are among the many people that were misled into adding Dichtelbach Jacob to an internet site, please try to correct that ASAP.
